Heer is a Bluetooth device detector that utilizes BLE technology to identify Bluetooth Low Energy devices and other Bluetooth accessories in your vicinity. It offers practical use cases such as locating lost phones or wireless earphones and detecting hidden or unwanted Bluetooth devices.

To prevent interference from your own Bluetooth devices, Heer includes a feature to exclude specific devices during startup, ensuring accurate detection. Additionally, the app addresses the limitation of background Bluetooth scanning through innovative solutions. Users can seamlessly continue using their iPhone with the help of a companion Apple Watch app, disabled auto screen lock feature, or guided access lock for enhanced security and uninterrupted functionality.
